theory to colloid particles flowing through a porous media, attraction and adhesion to media surfaces occurs when a particle passes at small separation distances for the media and particle surfaces (including their coatings) to interact with each another.
The inset shows the energetic balance of the phenomenon according to the Derjaguin and Landau and Verwey and Overbeek (DLVO
) theory as explained in the text.
The classical DLVO
theory is a quantitative theory of the stability (aggregation or dispersions) of charged colloidal particles, which was developed and published independently by Derjaguin and Landau in Russia in 1941 and by Verwey and Overbeek in Netherlands in 1948 .
interactions between spherical particles and rough surfaces.
From the experimental point of view the framework for calculating the electrostatic potential of a charged system involves the equations of classical electrostatics and is treated in the framework of DLVO
According to the DLVO
theory, the aggregation stability of DPG in certain conditions is determined by its gravitation and repulsion.
Energy barrier of aggregates coal particle-bubble through the extended DLVO
La modelacion matematica de esta fenomenologia es la teoria DLVO
, desarrollada por Derjarin, Landau, Verwey y Overbeck .
Esto genera que las fuerzas electroestaticas, de van der Waals y de atraccion de Born, que se pueden representar a traves del potencial Zeta, aumenten significativamente como lo indica la teoria DLVO
 y .
